Twisting device

Technical field

The drive motors that the present invention relates to drive spindle axis is located on same with this spindle axis, the twisting device of twisting thread that is undertaken by the rotation of this spindle axis.For example relate to the twist thread twisting device of processing machine of a kind of single-spindle driven, a plurality of twisting devices are set up in parallel, on each spindle axis, be provided with to drive and use motor, be particularly related to a kind of twisting device, can load onto spindle axis and constitute the drive motors of each spindle, and spindle axis be inserted or extract in the drive motors and uncorrelated with the rotor of drive motors.

Background technology

In the past, the known a kind of individual-spindle-drive type multiple twister of people is provided with coaxial with it drive motors on each spindle axis, by the rotation of this spindle axis, around the yarn feeding tube yarn is reeled and twisting.As this multiple twisting machine, known for example have once rotate single-spindle driven two-fold twisting machine by spindle axis to twice of yarn twisting.As this two-fold twisting machine, motor housing is contained on the down rail as supporter, in spindle fixing on this motor housing inner peripheral surface, inserts the spindle axis that rotor directly is fixed on outer peripheral face, thereby the formation drive motors, such twisting machine is just under development.

Directly be fixed on rotor on the spindle axis as a kind of, the example of structure that in the stator of drive motors, this spindle axis can be inserted or extract, spindle axis is not fixed on the supporter, can be with spindle axis with respect to supporter and be fixed on the twisting spindle axle (opening flat 3-14636 number) that the stator on the supporter is loaded onto and taken off with reference to the spy.Specifically, rotor directly is fixed on the spindle axis, the inboard of the sleeve of installing on supporter is freely loaded onto axle sleeve and is taken off, and by dispose bearing between this axle sleeve and bearing, spindle axis can be supported with rotating freely by sleeve.In such structure, because spindle axis is not fixed on the supporter, axle sleeve can be loaded onto and taken off with respect to sleeve, make spindle axis easily load onto and take off with axle sleeve.

Because the rotary speed of spindle axis directly influences the twisting count of twisting thread of production, in order to obtain high-quality twisting thread, the rotary speed of drive motors correctly maintains required predetermined value in the processing of need will twisting thread.Therefore for the single-spindle driven that drive motors is set on a plurality of spindle axis processing machine of twisting thread, inhomogeneous for the quality of twisting thread that do not produce each spindle need carry out quality examination respectively to a plurality of drive motors.In the quality examination of drive motors, the drive motors rotation is driven, the intensity in mensuration magnetic field and voltage, current value.For example, when stator uses permanent magnet, be fixed on spindle axis on by joint rotor after, this rotor is gone up the magnetic operation, will comprise insert (the comprising rotor) insertion of spindle axis thereafter, thereby can constitute drive motors.

But, as mentioned above, when directly being fixed on rotor on the spindle axis, then can not constitute drive motors owing to spindle axis is not inserted, can produce the problem that spindle axis then can not carry out quality examination of not loading onto.That is, after needing at first the rotary body that comprises spindle axis to be finished balance adjustment operation, this spindle axis is contained in the drive motors, practically the drive motors rotation is driven to check on the quality thereafter.Therefore can not carry out above-mentioned balance simultaneously and adjust operation and quality examination, particularly very inconvenience under the situation of using a plurality of drive motors.

And when directly being fixed on rotor on the spindle axis, spindle axis and rotor are loaded onto integratedly and are taken off, and therefore under the situation of changing the change of bearing and condition, rotor around the contact, might produce damage easily when spindle axis was inserted or takes out.

And because the condition change, when the insert that comprises spindle axis is changed, for example in double twisting machine, for obtaining different yarn feeding diameters, and when the diameter of rotating disc etc. changed, if when rotor directly is fixed on the spindle axis, also need spindle axis and rotor are changed together, be a kind of waste to using the high rotor of price especially, and after replacing, need to carry out once more the quality examination of drive motors.In addition when carrying out bearing replacing, to be fixed on the rotor on the spindle axis and when taking out bearing, need to make the external diameter of bearing bore diameter in order not influence greater than rotor, bearing diameter is restricted.Because it is big that bearing diameter becomes, durability reduces when rotating at a high speed.
